GUSTAVE J. ORIKELAIR, OF NEW V YORK, N. Y.

FIRE-ALARM.

SPECIFICATION forming part of Letters Patent No. 317,931, dated May 12.,1885.

Application filed April 27, 1883. Renewed September 5, 1884.

To all whom it may concern:

Be it known that I, GUSTAVE J. CRIKELAIR, of the city, county, and Stateof New York, have made certain new and useful Improvements inFire-Alarms; and I hereby declare the following to be a full and cleardescription and specification of my said improvements,

reference being had to the annexed drawings, in which- Figure 1 is aperspective view showing a room with wall in section. Fig. 2 is a viewof the outside casing covering the alarm-cannon. Fig. 3 is a View of thecannon with the case removed. Fig. 4. is an end view showing thearrangement of cannon and casing, and Fig. 5 is a section through Fig. 3on the line m w.

The objectof my invention is to give an alarm in case of fire.

In Fig. 1 the arrangement of my improved apparatus as applied to a roomin a house or other building is shown. Near the ceiling on the sidewall, or at other convenient place, I

secure a quick-burning fuse, A, extending around the room, or to allparts where any fire will be most likely to come. This fuse at aconvenient point is carried through the side wall to the outside of thebuilding and enters the touch-hole of a cannon, B, which should be ofsuitable size to sound the desired alarm when exploded.

In order to protect the cannon B from rain or dampness, I provide itwith a shield or cover, U, as shown in Figs. 2 and 4, and in order tostill further protect the fuse, the touch-hole is provided with a tube,D, which will extend into the wall, as shown in Fig. 5, and the fuse maybe conducted through the tube to the cannon or gun B.

(No model.)

In conjunction with the cannon B, the fuse may be connected withpackages of fire-extinguishing compound F, so that the alarm of firewill be given by the cannon and the fire-extinguishing compound beignited and set in operation by the same fuse.

In cases of isolated buildings, it is of importance to know when a firefirst commences to burn, and it is in such cases that my invention willbe of most service, although it may be used to advantage in allbuildings.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a fire-alarm, the combination of the alarm-gun B and itsprotecting-cover 0, located on the outside of a building, with theconducting-fuse connected thereto and. passing through the wall into thebuilding, where-- by, in case of a fire within, an alarm may be soundedwithout the building, all substantially as described.

2. The cannon B, located on the outside of a building and adapted to befired by a fuse, A, in combination with a fire-extinguishing compound,also connected with said fuse and located inside of the building.

3. In a fire-alarm, the combination of the alarm-gun B and itsprotecting-cover G, located on the outside of a building, the tube D,rigidly connected thereto and passing into the wall, serving as aprotection for the fuse A, together with said fuse, which passes throughthe tube and within the building, whereby an
